Publication - Distribution and diversity of cyst nematode (Nematoda: Heteroderidae) populations in the Republic of Azerbaijan, and their molecular characterization using ITS-rDNA analysis(Organization of Nematologists of Tropical America, 2019) Dababat, A.A.; Muminjanov, H.; Erginbas Orakci, G.; Ahmadova Fakhraddin, G.; Waeyenberge, L.; Yildiz, S.; Duman, N.; Imren, M.Cereal cyst nematodes (Heterodera spp.) are a significant threat to global cereal production systems and choosing the correct management strategy requires knowledge and identification of various species. We conducted a survey across the main cereal-growing regions of the Republic of Azerbaijan in 2017. Cyst-forming nematodes were detected in 34 samples (44.7%), of which 28 were identified as H. filipjevi or H. avenae using internal transcribed spacer (ITS)-rDNA sequencing. Six populations were unidentifiable to species level and were recorded as belonging to the H. avenae group. H. filipjevi was the dominant species, found in 19 samples (25%) from the provinces of Qobustan, İsmailli, Oguz, Sheki, Barda, and Kurdamir. H. avenae was detected in 9 samples (11.8%) across the provinces of İsmailli, Oguz, and Sheki. ITS-rDNA phylogenetic analyses showed that populations of H. filipjevi clustered in one group with two subgroups, all supported by high bootstrap values. Populations of H. avenae also clustered in one group with two subgroups. Genetic dissimilarities were higher within populations of H. filipjevi when compared to populations of H. avenae. The density of many of these cyst populations approached or exceeded the maximum threshold level for economic losses. This is the first report on H. filipjevi and H. avenae in Azerbaijan. The knowledge of cereal cyst nematode presence is extremely important for Azerbaijan’s agricultural industry when assessing the occurrence and distribution of soilborne diseases. Management measures to control cereal cyst nematodes should be directed towards breeding for resistant germplasm, crop rotation, and implementing other management practices.
Publication - Genome-wide association study for multiple biotic stress resistance in synthetic hexaploid wheat(MDPI, 2019) Bhatta, M.R.; Morgounov, A.; Belamkar, V.; Wegulo, S.N.; Dababat, A.A.; Erginbas Orakci, G.; Moustapha El Bouhssini; Gautam, P.; Poland, J.; Akci, N.; Demir, L.; Wanyera, R.; Baenziger, P.S.Genetic resistance against biotic stress is a major goal in many wheat breeding programs. However, modern wheat cultivars have a limited genetic variation for disease and pest resistance and there is always a possibility of the evolution of new diseases and pests to overcome previously identified resistance genes. A total of 125 synthetic hexaploid wheats (SHWs; 2n = 6x = 42, AABBDD, Triticum aestivum L.) were characterized for resistance to fungal pathogens that cause wheat rusts (leaf; Puccinia triticina, stem; P. graminis f.sp. tritici, and stripe; P. striiformis f.sp. tritici) and crown rot (Fusarium spp.); cereal cyst nematode (Heterodera spp.); and Hessian fly (Mayetiola destructor). A wide range of genetic variation was observed among SHWs for multiple (two to five) biotic stresses and 17 SHWs that were resistant to more than two stresses. The genomic regions and potential candidate genes conferring resistance to these biotic stresses were identified from a genome-wide association study (GWAS). This GWAS study identified 124 significant marker-trait associations (MTAs) for multiple biotic stresses and 33 of these were found within genes. Furthermore, 16 of the 33 MTAs present within genes had annotations suggesting their potential role in disease resistance. These results will be valuable for pyramiding novel genes/genomic regions conferring resistance to multiple biotic stresses from SHWs into elite bread wheat cultivars and providing further insights on a wide range of stress resistance in wheat.
Publication - Determination of resistance in winter wheat genotypes to the dryland root rots caused by Fusarium culmorum in Turkey(Bolu Abant Izzet Baysal University, 2018) Erginbas Orakci, G.; Morgounov, A.; Dababat, A.A.The dryland root rot (foot/crown) caused by Fusarium spp. attacks cereals especially wheat and causes severe yield loss by reducing both grain quantity and quality. Among those Fusarium species attacking wheat crop is the Fusarium culmorum species which has been reported as the main crown rot causal agent in Turkey. Unfortunately, up-to-date, there is only some wheat genotypes with partial resistant to Fusarium spp. Therefore, this study was carried out to find new sources of resistance in diverse wheat genotypes to limit the damage caused by Fusarium disease. In this study, a total of 141 genotypes and breeding lines were obtained from 19 different countries, provided via the International Winter Wheat Improvement Program (IWWIP) and screened for their resistance reactions to a local isolate of Fusarium culmorum under three different environmental conditions (growth room, greenhouse and field) in Turkey in 2012. The best performed genotypes in terms of resistant were then rescreened in 2013 for data validation. Out of the 141 phenotyped wheat genotypes, 17 genotypes (12 %) ranked as moderately resistant (MR) at seedling and/or adult growth stage. The genotypes from Mexico seemed to have adult plant resistant rather than seedling resistance which was higher in the USA genotypes. Winter bread wheats PATWIN YR5 and TAST/SPRW//ZAR/5/YUANDONG 3/4/PPB8- 68/CHRC/3/PYN//TAM101/AMIGO which possess high level of resistance seem promising for breeding for foot rot.
